A liquid level indicator for an oil-filled transformer, power choke or tap changer in which a sensor part has a float which rises and falls with the oil level and rotates a sensor shaft and the sensor shaft is coupled to an indicator shaft on which a pointer is provided to cooperate with a dial. The gauge also includes a contactless angle encoder operating with a magnetic hub and coupled to the indicator shaft for outputting a signal representing the oil level.
